In the present study, polyurethane materials were obtained from castor oil, polycaprolactone and isophorone diisocyanate by incorporating different concentrations of chitosan (0.5, 1.0 and 2.0% w/w) as an additive to improve ...

Elastomeric polyurethanes were prepared from a reference polyurethane system modified with biobased polyols synthesized using rapeseed or palm oils. The reference material was modified by replacement of the commercial ...

This study reports the preparation of polyurethane adhesives using polyols obtained from castor oil modified by a transesterification reaction with pentaerythritol and starch modified by glycosylation. The physical properties ...

This research presents the kinetic studies on the cure reactions of a new material, castor oil-based polyurethane resin. Thermal analysis by isothermal differential scanning calorimetry was used, as a variety of factors ...

Fibrous nanostructured polyurethane composite membranes were developed using electrospinning process. Membranes of polyurethane having silver and zinc oxide as additives were prepared by electrospinning of solutions having ...

Novel linear carbohydrate-derived [m,n]-polyurethanes are successfully prepared using d-mannitol as renewable and low cost starting material. The key comonomer, 1,6-di-O-phenylcarbonyl-2,3,4,5-tetra-O-methyl-d-mannitol is ...

This study is the validation for a new method to introduce a new color coating in the fabrication of electric guitars, before this, the time for the validation was 20 to 25 days. This new validation reduced the time to ...
